More than a week had passed, and life in the Star Tribe had returned to normal since the bonfire party. The arrival of the Black Sheep Warriors had added a lot of manpower to the entire tribe.

The two parties are always not in harmony because of the previous reasons. Su Yuan doesn't have any particularly good solution for this. As long as nothing happens, it can only be like this for the time being.

During this week, Su Yuan was not busy with other things. He had been debugging the balanced ratio of the Yanwen iron ore. Without modern machines, he could only use the simplest method.

Trying one by one is also called the controlled variable method.

During the scientific research process, I just played with cats, foxes, and lions. The temperature outside was getting colder and colder. Even if I wrapped myself warmly, I would still feel the biting cold when I left the light range of the camp.

So Su Yuan had to give up teasing foxes and cats at the hot springs, and he did it secretly in his own cabin every time.

Fortunately, the Molten Guardian Orb does not drive away the sound of the cold wind. During this period, the noisy wind around the camp every night covers up the joyful sounds of the night.

In the early morning, the weather was as gloomy as usual. Su Yuan sat on a short wooden stake and studied the freshly-made flame-patterned iron ore.

"The 218th time, 3 hours, 15 minutes and 12 seconds."

Su Yuan pressed the stopwatch he exchanged for. The balance of the flame-patterned iron ore was accurate to the second, so he had to buy a stopwatch for precise timing.

In his hand, the color of the fire-patterned iron ore was completely different from before, and the blood-red gem fragments returned to their previous orange-red color.

If you look closely, you can clearly see the blood-red lines and ice-blue veins flowing in it. The fire element and water element are entangled in the ore body and finally gather in the center.

Unfortunately, the blue eventually completely swallowed up the red in the center of the ore, and the iron ore still did not reach balance.

[Note: Ordinary iron ore is transformed into flame-patterned iron ore by the blazing fire crystal. After being refined by human error, it absorbs a large amount of fire pyrolysis, and then absorbs a large amount of water pyrolysis in the water. The pyrolysis force in the ore is slightly unbalanced, and there is a very small probability of explosion.]

"There was too much pyrokinesis in the previous 10 seconds, so it looks like it will be 15 minutes and 11 seconds."

Su Yuan opened the small notebook he carried with him, which contained Ton Ton Mama's data.

More than a week of continuous testing had made him a little irritated. If it weren't for the fact that this thing was dangerous and the timing statistics were a little complicated for these beast girls, he would have just let it go.

"The water element has expired, so we can only refine a new batch..."

"Su Yuan, the Frost Crystal Season is coming!"

At this moment, the fox came running over from behind with some concern, followed by the black sheep. After a week, her body had recovered a little.

The spider silk on his hands and feet was not untied, but compared to the tight binding before, it was no problem for him to move and do things now.

"Frost Crystal Season?"

Su Yuan looked up at the sky. He had been so busy studying the Yanwen Iron Ore that he didn't notice that the weather had been gloomy for several days in a row.

The frost crystal season that the foxes were talking about couldn't be winter? How could there still be winter in this icy and snowy place when it's so cold?

"The Frost Crystal Season basically only occurs every few years, and each one lasts for seven or eight days at the shortest, and even several months at the longest."

When the Frost Crystal Season was mentioned, Black Sheep showed some worry on his face, and continued slowly: "Every time the Frost Crystal Season appears, many people die. Some people get lost in the snow while hunting and freeze to death, and some people starve to death because the tribe does not have enough food to survive the Frost Crystal Season."

According to the ancient legends of primitive tribes such as the Fox and the Black Sheep, the Frost Crystal Season is the sad day of the gods. Every time this time comes, the sky will be gloomy and a layer of cold fog will cover the snowfield, making it impossible to see the road clearly.

The animals all look for places to hide, and the trees and grass in the snowy fields are covered with a layer of crystal ice, which is why it is called the Frost Season.

Su Yuan nodded thoughtfully. This kind of weather was somewhat similar to the freezing weather in his hometown before he traveled through time, but the frost crystal season in this alien world was probably even more terrifying.
